摘　　要：2012年至2016年,连续5年以伊犁河谷中山带山地草甸类、温性草甸草原类和温性草原类退化草地为研究对象,测定其围栏内外的鲜草产量、干草产量、植被盖度、草群高度和植物种类。结果显示:围栏封育可以有效提高退化温性草原类、温性草甸草原类、山地草甸类草地的生产力;能显著提高3类草地的鲜草产量、干草产量和草群高度;对植被盖度的影响随着海拔的升高逐渐降低;对植物种类数的影响幅度较小,差异不显著(P>0.05)。说明围栏封育可以作为草地改良的措施之一在伊犁河谷退化草地中应用。Mountain meadow,temperate meadow steppe and temperate grassland degraded grassland in the middle mountain in Yili River valley were used to examine the fresh yield,hay yield,vegetation coverage,vegetation height and plant species inside and outside fence for 5 consecutive years from 2012 to 2016. The results showed that the fence effectively improved the grassland productivity in the degraded temperate grassland,temperate meadow steppe and mountain meadow grassland; significantly improved the fresh yield,hay yield and grass height of the three types of grassland;the influence on vegetation coverage gradually decreased with altitude increasement;the impact on plant species was not significant（P＆gt;0.05）. It could be concluded that fence would be used as a grassland improvement measure in degraded grassland in Yili River valley.
